National Geographic’s ongoing photo series “Patterns in Nature” focuses on food this week, and the result is 10 mouth-watering images that can be downloaded as wallpaper for your desktop. From the spiky spring green of durian fruit to the stony blue of a pile of steamer clams, the colorful images practically beg for smell-o-vision. The little tidbits with each photo are nice, too; for example, did you know that “[m]ore than 400 types of seafood … are sold at Tokyo’s Tsukiji fish market”? What a nice little holiday giveaway. Please, refrain from licking your screen when the blueberries-and-milk image comes up.
